He did he work could present for several years broke over the Iraq War. We and and I was there for the first five years administration as you say broke over the Iraq War I think it was a great moment these are always great moments that happen with the the five living presidents there. They pay respects regardless of party. Libraries in presidential institution being an important part of our cultural and and researching conversation and I think the president. You know reflecting back had done a number of good things what he -- for aid to Africa. As Don has pointed out what he did two in the aftermath of Katrina and a number of things and I think what you saw was everybody thinks this is a good man but the problem that I signed this whole thing. As we -- that they everybody focused on it it's as if you were asking the people that got off the Titanic they say other than that how was the trip. And. The Iraq War with the disaster we spent over a trillion dollars we lost thousands of lives -- on that serve there. And we lost thousands of US -- thousands of lives over in Iraq. And the Iraq War for at least twenty years is in effect this already affecting our foreign policy in Syria. It's if it's caused the president to not sit well I don't know if I can do this because of what happened Iraq War it's our fact that our domestic policy because the lack of funds that lack of ability and it polarize the country. And so I think we paused for a moment we say yes he's a good man but in the end the Iraq War was such a disaster decision in effect of this country so dramatically. His -- history is going to be completely tied to that.
